A SEVERE weather warning will remain in place into tomorrow as wild winds and rain continue to lash the southern half of the state for the next 24 hours.

Gusts over 90km/h have knocked down several trees, blocking roads, while the accompanying rain has caused some isolated minor flooding.

State Emergency Service crews have attended more than 170 incidents, and more are expected throughout the day.

Senior meteorologist Brett Gage said the severe weather warning would remain in place until tomorrow, when the rain and winds should ease in the afternoon.

“There is a very intense low to the south, in the Southern Ocean,” he said.

“A polar front jet is wrapped around that low, which will remain.”

The bureau last night issued a severe weather warning for the damaging winds.

The warning was for people in the Adelaide Metropolitan, Mount Lofty Ranges, Lower Eyre Peninsula, Yorke Peninsula, Kangaroo Island, Mid North, Upper South East, Lower South East and parts of the Eastern Eyre Peninsula and Murraylands districts.

Mr Gage said rain and wind gusts would continue into the night and would only begin easing off tomorrow afternoon.

Gusts of 93km/h were reported at Adelaide Airport and Mt Crawford, while a 98km/h gust was reported at Hindmarsh Island.

Several locations across Kangaroo Island have recorded gusts of 90km/h.

To 11am, he said about 13mm had been recorded at Kent Town. Regency Park recorded 20mm, while Adelaide Airport had registered 8mm.
